I tried this some time ago and didn't get even a hint of a nibble.  I thought I'd try again.
Isn't there a C4 owner out there who's contemplating some kind of change?  Wouldn't you like to see your C4 united with it's soul-brother, my Music Reference EM7 amp?  Wouldn't it warm your heart to know that I was enjoying my magnificent tunes through the marvelous RAM tubeage thanks to your well-timed sale?
Come on.  Make us both happy.  Sell me your C4.
